Which PDF tool should you use and when?

When you need to share several PDF files such as contract attachments, invoice packs, or presentation notes as a single document, the Merge PDF tool is a good starting point. You can add files in order and check the page layout in the preview before exporting.

Merging appends the page content of source files one after another; text and images usually remain as they are. Still, different page sizes or mixed portrait and landscape pages may look unusual in one PDF file, so scrolling through the output before sharing is a good habit.

Do not delete the original source files; merging creates a new copy. With many files or very large files, you may hit browser memory limits. In that case, removing unnecessary pages first or merging files in smaller groups may help.

When you need to send only one section of a long report, a signature page from a contract, or selected pages from a manual, consider the Split PDF tool. Page ranges, individual page numbers, or exporting every page as a separate file can fit different needs.

Splitting exports the pages you choose as a new PDF; the source file you uploaded stays unchanged in your browser session. Before downloading the output, checking the page count and the first and last pages helps catch wrong range selections early.

If you only want to extract one or two pages, splitting may be enough. If you need to remove many unnecessary pages, the Delete Pages tool may produce fewer files. Before trying both, clarify your goal: do you want to extract and keep selected pages, or clean the rest of the document?

When blank scan pages, old attachments, or sections you do not want to share remain in a document, the Delete Pages tool removes the pages you mark and creates a new PDF from the rest. Thumbnail previews help you visually choose which pages should be removed.

If page order matters, the Reorder Pages tool lets you arrange pages with drag and drop. For example, when scanned documents need to be placed in chronological order or presentation slides need rearranging, fixing the order before deleting pages may save work.

Deleting and reordering change the page structure of the document; the text quality of remaining pages is usually preserved. Still, for critical documents, opening the output once and checking page numbers and orientation is useful, especially for court files or official paperwork.

For sideways scanned pages or slides saved in the wrong direction, the Rotate PDF tool turns selected pages in 90-degree steps. You can target the whole document or only a few pages, and preview the result before downloading.

When you want to add a visible mark such as "Draft", "Confidential", or a company name, the Add Watermark to PDF tool applies a text or image watermark. A watermark is used to show the status of content before distribution; it does not encrypt or legally lock the document.

Watermarking and rotation can make permanent visible changes to the output, so make sure you selected the right pages before sharing. For sensitive drafts, creating a watermarked copy and keeping the original separately can reduce the chance of sending a clean version by mistake.

You can use the Image to PDF tool to collect photos, screenshots, or scanned JPG/PNG files into one PDF file. Order and page size options are especially useful when archiving multiple images in a single document.

To use existing PDF pages in slides, social media, or editing software, the PDF to Image tool exports pages as PNG, JPG, or WebP. The resolution preset balances file size and clarity, but it may not always be enough for print-quality output.

Conversion can turn vector text into pixel images, which means text selectability may be lost. If the text needs to remain editable, prefer tools that work directly on the PDF instead of converting it to an image; always test the output for your purpose.

The short matching list below is a starting point for the common "which tool?" question. Complex workflows may require more than one step; checking the intermediate file after each step is a good practice.
